Application filed March '16, 1920. Serial No. 366,260;

To all whomz't may concern:

Be it known that I, HUBERT CHIPPENDALE SMITH, a subject of the King of Great 'Britain and Ireland, residing at 61 Copley Hill, Erdington, in the city of Birmingham England, have invented certain new Burners, of which and useful Improvements Relating to Gas fication.

This invention relates to gas burners, particularly'of the incandescent type, and has for its object to provide simple and convenient means for the adjustment or regulation' of the gas jet or jets to suit varying conditions and requirements; I

In the accompanying sheet of explanatory drawings V Figure 1 is a part sectional elevation of an incandescent gas burner nipple fitted with an adjuster in accordance with this.

invention, and Fig. 2 is a plan of the same.

In the application of the invention as shown to the nipple of an incandescent gas burner, the jet adjuster or regulator is made from a phosphor bronze or other wire having one end fiattenedto form a sliding or oscillatory plate or valve a to pass over the small gas orifice b or orifices formed in the outlet end of the gas nipple c or its equivalent. The said wire is bent at right angles to form a stem (Z which is inserted in an aperture drilled longitudinally through the nipple, parallel with the gas way or conduit 6 but having no communication there with. The wire is also bent at right angles to form a lever f and its outer end is coiled around or otherwise attached to a button or finger grip g; or such end of the Wire may itself be made to serve as a finger grip.

At the end of the said longitudinal apertture adjacent to the lever f a recess h is formed in the nipple with an open side such as will provide an abutment at one s ide to limit the opening movement of the lever f. The said recess serves also to prevent projection of the adjuster beyond the adjacent I end face of the nipple such aswould obstruct the attachment or screwing of the nipple on to the gas supply fitting in the ordinary manner. I

yond the outer a face of the valve. the following is a speclters Patent is when the sliding plate or valve such as aforesaid is moved across the same,,the nipple is stepped or recessed adjacent to the valve asshownso that the nipple extends on one side of the valve to or slightly beadapter :may be otherwise modified in its details and in the complete device to meet varying services or requirements.

In the position shown in the drawings the valve is in the closed position, or the posi tion for producing a minimum flow of gas through the nipple. n1 'this'position one end of the operative edge of the valve abuts against the shoulderformed by the stepped portion of the nipple; The said edge of the rection of the arrow (Fig. 2) causes the nipple aperture to be progressively opened. At the limit of movement the nipple aperture is fully open. I

Having thus described my invention what I claim as new and desire to secure by Letvalve is made to an eccentric curved form, so
